We are mixing the use of dumb/stupid a bit. I do not think Cam is a smart person, but I think he is more unntelligent as a football player. I am referring to a "sense" or "feel" but there is some intelligence behind it too. However, this coaching staff dubbed themselves as teachers, something I see no evidence of at all, so I see your point. Would Cam prosper under Harbaugh? Maybe not, because Luck and Alex Smith are very smart. However, Kaepernick is a lot like Cam, and he is doing OK. Who knows, but we are going to find out.
If I have Cam, I hire a coach who has a record of getting the most out of QBs. When I think of Bill Cowher and his success with Stewart, Maddox, Ben--I have to think he gets it.
My first choice, however, is Kelly from Oregon.
I am not sure these guys make QBs better, but they make everyone around the Qb lift the QB's game.
I have seen nothing to suggest that Cam is anything other than completely normal and average in intelligence level. Don't confuse a person's vocabulary or their use of mixed metaphors as indicators of intelligence. Many southerners, for example, speak in a manner that northerners find overly simplistic. That is certainly no reflection on their intelligence.
You apparently believe that Cam has mental challenges above and beyond the norm; I certainly believe otherwise. That's okay, no one says everyone has to agree.
Give the kid good coaching and then we can talk.
